[detailed description of the invention]
Below by instantiation, present disclosure is further described.
Deformable Volumetric hologram implementation method, comprises the following steps:
(1), obtain line holographic projections or the objective image shown by display device current display interface as actual image, obtain
Take observer relative to the most appreciated subjective image shown by line holographic projections or display device current display interface
For hologram；
(2), the amplitude that calculating actual image needs are elongated:
A is as it is shown on figure 3, setting actual image is to be projeced on horizontal plane, and as shown in Figure 4, hologram is relative to level
Vertically getting up of vertical 90 ° of the actual image in face；
B, the amplitude of elongation to be calculated, the eye level of hologram to be set is H, as shown in Figure 5 and Figure 6, described
The eye level H of hologram is without departing from the visual range of observer；Wherein, the eye level H of hologram and actual image
Length be relative, in other words, it is possible to first preset the length of actual image and draw the eye level of hologram；
C, as shown in Figure 6, determines that observer is D with the distance of hologram；
D, as shown in Figure 6, determines that the height of the actual image of observer's eye distance is Y；
E, as shown in Figure 6, determines a length of X of actual image；
F, assume that the numerical value of D, H and Y is to preset detectable, actual shadow can be calculated according to the geometric ratio formula of triangle
As the numerical value corresponding to length x, the length of the required stretching of actual image；
Such as, distance D of observer and hologram is 2 meters, the eye level H of hologram from display plane (as
Face) 90 degree vertically hold up, and eye level H is 1 meter, and estimation observer's eye distance display plane (such as ground) is about 1.7 meters,
The i.e. height Y of the actual image of observer's eye distance is 1.7 meters.
As it is shown in fig. 7, A=2.625
∵ tan (a)=1.7/2
∴ a=40.365 °
B=180 °-a=180 °-40.365 °=139.635 °
C=90 °-a=90 °-40.365 °=49.635 °
∵ tan (d)=sin (c) ÷ (A-cos (c))=sin (49.635 °) ÷ (2.625-cos (49.635 °))
∴ d=21.073 °
E=180 °-b-d=19.292 °
∵ tan (e)=tan (19.292 °)=1 ÷ X
∴ X=2.857
Form 1 meter of high hologram, a length of 2.857 meters of actual image the most in this embodiment.
(3), the proportion of deformation of the actual image nearby and faraway of adjustment:
A, actual image are after elongating, and as shown in Figure 8, make up the angle formed because of observer and actual image, and make
The eye level H correspondence change of hologram, causes the part that actual image is nearer relative to observer, visual effect the most nearby
Upper meeting is bigger；Cause simultaneously actual image relative to observer's part farther out, can be less in visual effect i.e. at a distance, actual shadow
The nearby and faraway of picture relative to observer owing to producing the distortion in visual effect apart from upper difference；
As it is shown in figure 9, need actual deformation of image, make up because image different piece and observer have different distance, and
Cause the deformation of visual image；Such as, image distance observer's part farther out is drawn wealthy, i.e. amplifies；
Proportion of deformation needed for b, the actual image nearby and faraway of calculating, its proportion of deformation formula is:
R=Lmin÷Lmax,
R be on actual video vision the most nearby with the size proportion of deformation of farthest, LminFor observer and actual image
Distance nearby, LmaxDistance for observer Yu actual image farthest；
C, needs, an actual deformation of image, by image processing software, adjust actual image farthest and are arranged to actual shadow
As the most nearby R times, for making up actual image different piece and observer due to its nearby and faraway apart from upper different
And cause visual deformation；
As shown in Figure 10, it is assumed that image is the most nearby from observer's distance LminBeing 1 meter, image farthest is from observer's distance
LmaxIt is 2 meters, Lmin=1, Lmax=2, so R=0.5；So the vision size (width) that actual image is the most nearby is relatively " actual
Image " vision size (width) ratio of farthest is exactly 2: 1, so actual deformation of image need to be made actual image farthest
It is set as 2 times the most nearby of actual image.
(4) difference of the actual image of right and left eyes, is adjusted
A, through step (2) and the calculating of (3) and process, actual deformation of image, make up because of actual image and observation
The angle and distance that person is formed is caused visual deformation of image；But because observer can process shadow through eyes and brain
Picture, tells the image distance relative to eyeball, as shown in figure 11, and analyses erecting of broken image non-real；Need to be passed through last
The image processing of step, the brain of deception observer so that it is takeing for image is phase with farthest relative to observer's distance the most nearby
Deng, i.e. hologram is upright if 90 degree, thus results in image and projects in the eye of observer as the hologram erect；Tool
Body is, by 3D display device, actual image part farther out is caused visually near than reality, or nearer for actual image
Part causes visually remote than reality；Or actual image part farther out and nearer part are processed, i.e. actual shadow simultaneously
As part farther out cause visually near than reality while, also part nearer for actual image is caused visually than reality
Far, make the left eye of observer and right eye be respectively seen no image, thus cheat the brain of observer, cause visual illusion shape
Become actual image is equal visual effect with farthest relative to the distance of eyeball the most nearby.
As shown in figure 12, the adjustment amplitude of right and left eyes image, by distant place image part is pulled to how close decision or nearly
Place's image part is pushed into and how far determines or simultaneously an image part at a distance be pulled to how close and will divide and how far be pushed into by image part nearby
Together decide on.
The present invention is calculated or estimated observer and produces position and the distance in place relative to image, is calculated or estimated, and
By result, image is carried out torsional deformation process, cause visual artifacts；So-called torsional deformation processes, the most as shown in Figure 2
The principle of deformation process relief painting (anamorphic illusion).But under practical circumstances (and in non-photo), because of people
Class may determine that the distance of image at the moment with eyes；So only through the image of deformation process, being to cheat in reality
The brain of observer thinks that image is the effect towered or erect.Accordingly, it would be desirable to calculate further, image is reprocessed, make into
The image entering the left eye of observer and right eye is otherwise varied, produces on-the-spot holographic visual effect.
Therefore, through being calculated or estimated, image or anamorphose processes, then coordinates some 3D display devices, such as figure
Shown in 13, the present invention just can produce the three-dimensional illusion of tower (holographic) at the scene in environment；It can at horizontal plane, tiltedly
(surface of image display) is applied on the surface of face, curved surface or any angle；Vision imaging (artefact) can stretch out or go deep into shadow
Surface shown in as, and the vision imaging erect (hologram) can adjust the angle of setting on demand, is i.e. not required to be defined to hang down
Helicopter-9 0 °；And can be plane, three-dimensional hard photograph, or plane, 3-D cartoon for making the raw video about stereoscopic image,
Or plane, three-dimensional video video；And the treated the most exportable one-tenth of 3D image shines firmly, animation or video.The present invention's
Application can expand the 3D visual experience of observer, can apply to the environment different with tradition 3D stereoscopic approach and application simultaneously
On face.
It is exactly more than example and the principle of the present invention, it is necessary to it is emphasized that above calculating is model in actual applications
Example, calculation and processing mode can make corresponding adjustment in response to different-effect needs or the change of environmental factors；Example
As, when image is not that display (such as inclined-plane) or hologram are not to set that 90 ° are upright, image is vertical as computer 3D in a horizontal manner
Body image (on-plane surface image), hologram are absorbed in or are in (and non-protruding) etc. in horizontal plane shown below media, we
Will appropriately adjust on calculating or processing；But calculate and the basis of processing mode is all based on the former of implementation method of the present invention
The mathematics of reason correspondence adjusts.
Embodiment described above is simply presently preferred embodiments of the present invention, not limits the practical range of the present invention with this；
Except in the case of specific embodiment is enumerated, all equivalence changes made according to the principle of the present invention, the present invention all should be covered by
Protection domain in.
